| Summary: | 碩士 === 國立中正大學 === 機械工程所 === 96 === The analysis of the mesh stiffness in the nonlinear dynamic gear train was simulated by applying mathematical technique such as Fourier series, rectangular wave function. However, the error always exists between practical experience and mathematical technique.
This study is focused on the involute tooth profile of generation of the rack cutter and evaluated the mesh stiffness by using tooth profile. Furthermore, the effect of the mesh stiffness affected the non-linear dynamic behavior of the gear train. The generated parameters of the rack cutter included line and fillet parts, pressure angle, and tooth depth (which included root tooth, addendum, and clearance). These can affect the tooth profile and evaluation of the mesh stiffness. In this study, the parameters design how to affect the tooth profile, mesh stiffness, and non-linear dynamic behavior.
According to the results, the dynamic behavior of gear train was affected by the contact ratio and mesh stiffness. The system response was small for the gear train of high contact ratio as stable action at high speed. The response can be increased for high mesh stiffness. This theoretical model of system can be quickly solved response to pre-analysis a situation of the motion and selected the gear train in the mechanical transmission.
